SABELLIDES AND SERPULIDES

paratively few unequal serrations the lowest one long and fang-like 

 when seen in profile, but in a front view the broad surface has three or 

 four alternating series of slender teeth. With the exception of the 

 operculum these characters seem to agree with those of Josephella 

 marenzelleri Caullery and Mesnil (p. 226) ; the operculum is described 

 by these authors as being borne on the end of a branchia and as having 

 some calcareous deposit ; the Mediterranean species may be immature 

 and a fully developed operculum might have some lime deposit. The 

 tube recalls that of Filograna, one species of which {F. corallifica 

 Pallas 1766) is given by Morch, 1863, as from the Mediterranean; 

 since no further mention has been found of any similar form, the spe- 

 cies, notwithstanding the fact that the operculum appears also to differ 

 in having a definite peduncle, is referred to Josephella, as^. humilis, 

 but with considerable doubt.
